The Victoria Falls is the tallest waterfall on Earth measuring 108 meters at its highest point. How long will it take for a single drop of water to fall over its edge into the chasm below?

Please check answer, if I am doing it incorrectly help me set it up. the last person who tried to help gave me an answer that did not make any sense. Thank you

square root of 108/1/2 (9.8 m/s^2
square root 108m/4.9 m/s^2
t=4.695s

What don't you understand about my previous answer?

Use g = 9.8 m/s^2. I gave you the equation to use.
